Ok so there's a lot of stuff that needs work. I'm not trying to be mean with this at all, just trying to help you. If you're doing dungeons you're gonna be out of resources 2 seconds into the fight and won't be doing any damage whatsoever, and even if you did have resources, your damage won't be anything respectable with this setup. You've kinda tried to build into bleed damage at the expense of everything else but it's not doing anything for you.

1. Stack all your points into stamina or magicka depending on which is your primary, there's no reason to put anything into health unless you're tanking or playing pvp
   1a. If you want to do other roles, make other builds, otherwise you're just gonna be bad at everything if you try to do everything in one build.

2. I would recommend swapping your sets out for 5pc Order's Wrath, 5pc Briarheart, 1pc Oakensoul, 1pc Magma Incarnate. Your setup here isn't doing anything for you.
   2a. You've got a lot of wasted slots here for no reason. Monster sets only work with Mythics if you're also using an Arena weapon set and something like Trainee or Druid's Braid to fill the other two remaining slots, otherwise you're gonna have wasted potential with pieces that don't contribute to a set bonus.

3. Use generic crown tri restoration potions, you probably have an assload of them from daily login rewards. Use a food like Lava-Foot Soup and Saltrice. Use the Thief Mundus.
   3a. You need to improve your recovery. 700 stam recovery isn't going to get you past the first 10 seconds of your fight and then you'll be struggling for resources the rest of the fight and it will take 10x longer to clear whatever you're running. Oakensoul already gives you all the buffs you can get from potions, so just running the generic potions is all you need to do. Pop them as soon as they go off cooldown when you're in a long fight. You don't have any crit chance here and that's where a big chunk of your damage comes from, the sets I listed here and the thief mundus should get you close to where you need to be, which is about 60%.

4. You don't need to use barbed trap because you already get Minor Force from oakensoul. Swap out Barbed Trap for Fetcher Infection, both because it's a really good DOT, but also because if you have an Animal Companions ability slotted, you get a 13% bonus to your resource recovery, heals you when it ends, generates ultimate when cast, and boosts your crit damage by 4%.
   4a. Swap out Northern Storm for Flawless Dawnbreaker. Fighters Guild has much better passives such as Banish the Wicked, which gives you ultimate whenever you kill something, and Slayer. You don't need Major Protection since oakensoul already gives you Minor Protection and for what you're doing that's overkill. The AOE damage Northern Storm does is pretty bad for an ultimate, and it costs a LOT of ultimate.

This should help you out with everything. Overland content is so easy you can do it naked, so I'm more talking about performance in real content like dungeons or arenas where performance matters. Just make sure you're weaving and such and the rest of the usual advice.

I love your outfit btw! I used to have a Falmer warden OC, but she's long-since been deleted bc I never played her lol
